Hi Rich,
I googled for info on the RDL HR-DSX4 and found your posts.
Never got a reply from RDL about how quick the switching is (if there's latency when you switch - or switching noise, for that matter),
whether the feeds remain bit-transparent (output identical to input),
and if the HR-DSX4 applies sample rate conversion if the sources are different Fs.
Any help with these would be much appreciated.
Thanks,
